What? Facebook can get me stalked by women? Where do I join?
Jokes aside, I remember when the whole 'net thing began to take off and all sorts of social phenomena was (and still is) being discovered.
Guys and girls were suddenly finding creepy people turning up at their doors after breakups.
Police were getting all sorts of tip offs about crime and not all of them were guilty people.
People were getting ripped off sending (still are!) sending money to sob storied senders.
Explicit photos of ex-girlfriends/boyfriends sent to parents or schools where their kids were going to.
Companies were getting websites devoted to them (rightfully so sometimes) by disgruntled employees. Until recently, there was a website called "Bunnings is a shit place to work" in Perth and the company got it taken down. It was a shame because all the ex-employees told it like it is which prevented heartache for a whole lot of potential jobseekers.
One day, a dinner was organised for a whole bunch of expatriates at a restaurant in Hongkong. Everyone had a good time but were confused as the guy who booked the table didn't identify himself. The next day on the messageboard forum - the "organiser" revealed he was just some prankster posting from Venezuela but was pleased it turned out so well and people made new friends!
Facebook is just one of these phenomena!
